Australia has large reserves of a number of resource commodities other than iron ore and
coal, its two largest resource exports. These include copper, bauxite (the ore from
which aluminium is produced), zinc, nickel, lithium and cobalt.

Stronger global demand for these commodities, stemming from both cyclical and structural
factors, has contributed to significant price increases since 2016 (Graph C1). The
pick-up in global GDP growth over this period has resulted in a broad increase in demand
for commodities used in industrial production and construction, such as copper, zinc,
nickel and aluminium. In addition, the outlook for the global uptake of electric
vehicles and renewable energy generation has improved due to government policies and
improved cost competitiveness. This in turn has increased the demand for copper,
lighter-weight metals and commodities that are used in rechargeable batteries:

To help offset the additional weight of a battery, the body of an electric vehicle
is often manufactured with a higher share of lighter-weight metals such as aluminium
and copper compared with a conventional vehicle.

Renewable energy generation (wind, solar and hydro) uses copper more intensively
than coal- or gas-fired generators, partly because of the need for larger earthing
systems and longer transmission lines to connect to grids.

Renewable generation is also increasingly associated with battery storage systems,
including rechargeable batteries similar to those used in electric vehicles.

Australia is well placed to meet some of the increase in global demand for these
commodities. Around 20–25 per cent of known global reserves for bauxite, lithium,
nickel and zinc are located in Australia, and around 12 per cent for copper. Australia
was one of the largest five global producers for each of these commodities in 2016.[1] Mineral
exploration and mining activity for these commodities has increased over the past two
years, after several years of curtailed production and mine closures both in Australia
and overseas; stronger commodity prices have supported the confidence and the ability of
exploration and junior mining companies to secure financing.

As a result, Australian export volumes for these commodities are expected to increase
over the next few years, as new projects commence production, existing mines are
expanded, and mines that had been placed in care and maintenance are restarted (Graph
C2).[2]
Exports of copper and lithium are likely to drive the bulk of this growth; lithium
exports are expected to triple over the next few years. Exports of bauxite, zinc and
nickel are also likely to contribute to resource export growth, but to a lesser
extent.[3]

In aggregate, copper, aluminium and its ores, zinc, nickel and lithium account for a
small share of Australia's exports. In 2017 they comprised around 7 per cent of
total export values and 13 per cent of resource export values, which was a
similar share to liquefied natural gas (LNG).[4] However, this was
much smaller than the share of coal and iron ore, which comprised around 30 per cent of
total export values and 60 per cent of resource export values in 2017.

Despite the positive outlook for export volumes of these commodities over the next few
years, their share of total exports is expected to remain around the same as present. In
the period to 2020/21, their combined contribution to total export growth is likely to
average around 1/3 percentage point a year; this compares with a forecast average
contribution of around 1 percentage point a year from LNG over the same period.
Similarly, developments in export prices for non-ferrous metal exports are not expected
to materially affect Australia's terms of trade. Instead, iron ore, coal and LNG
will remain the most important for overall export prices, because they are still
expected to comprise around 40 per cent of Australia's export values in coming
years.

Looking beyond 2020, global renewable energy generation and sales of electric vehicles
are expected to continue growing strongly as they become more cost competitive. For
example, BP expects that, by 2040, renewable energy will account for almost 15 per cent
of global energy needs (up from around 5 per cent now), and that there will be more than
300 million electric vehicles on the road (16 per cent of the global car stock; Graph
C3).[5] All
else being equal, this should continue to support demand for Australia's non-ferrous
metal exports.

Alongside prospects for rapid growth in renewable energy production in coming decades,
gas may also meet a growing share of global energy needs over this period. This is
partly because government policy measures are favouring lower-emission fuels and
low-cost gas supplies are expanding. While increased global gas demand could support
further growth in Australia's LNG exports, this will depend on Australian LNG's
price competitiveness and whether global demand is met from pipeline or LNG sources.[6]

In addition to bauxite, Australia exports alumina and aluminium, but because no
additional refining and smelting production capacity is expected for these in
the next few years, it is not expected that they will add materially to export
volumes over this period.

As a share of resource export values in 2017: copper and alumina each comprised
around 4 per cent; zinc, aluminium and nickel each comprised a little under 2
per cent; bauxite and lithium comprised around ½ per cent each; and
cobalt comprised less than ¼ per cent.
